Title:
ILLUMINATION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3498967
Kind Code:
B2
Abstract:
PURPOSE: To gradually control the brightness of a load up to a target level based on the fade time data received from a controller when each control terminal equipment control the light of the load based on the light control data received from the controller.
CONSTITUTION: A central controller 1 transmits the fade time data to a control terminal equipment 2 to be controlled when the light control data are sent to the equipment 2 through a transmission path 5. Thus the equipment 2 receives both the light control data and the fade time data and then controls the light of a load 26 based on the light control data. At the same time, the equipment 2 performs a fade-in or fade-out operation based on the fade time control to gradually control the load 26 to a prescribed light control level.
